FROST-COCK FOR LOCOMOTIVE-BOILEBS.

Specification of Letters Patent.

Patented Dec. 9, 1913.

Application filed June 9, 1913. Serial No. 772,727.

To all whom it may concern Be 1t known that we, HENRY Jixcinnsni and JO N J. HOLOHAN, citizens of the .United States, residing at Gibson, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Frost-Cocks for Locomotive-Boilers, of which they following is a specification, ref erence being had to the accompanying drawings. v

This invention relates to new and useful improvements in relief cooks and more particularly to a relief cock adapted for attachment to a locomotive branch pipe, the object of the invention being to provide a relief cock which is readily applicable to. the branch pipe near the check valve to prevent the branch pipe from freezing up during cold weather.

Another object of the invention is to provide a relief cock of the above character which will possess advantages in points of efiiciency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

lVith the above and other objects in- View, this invention consists in the novel features of construction, and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, in which- Figure 1 is a side elevation, parts being broken away and in section; Fig. 2 is a detail side elevation illustrating the applica tion of our improved frost cock; Fig. 3 is a transverse section-LL view; and Fig. 4 is a top plan view.

Referring more particularly to the drawings, 1 indicates the branch pipe of a locomotive and the check valve which may be of any well known construction. Located within the branch pipe at a suitable distance from the check valve is our improved relief cook 3. In the construction of our improved relief cock we provide a body memher i which is substantially oval-shape in its construction and provided with an interior chamber 5, said body being provided at its lower end with an outlet opening 6 which is adapted to communicate with the chamber 5 and is normally closed by means of a removable plug 7. Removably engaged with the body member at and projecting at an angle therefrom is an outlet tube 8 which is adapted to communicate with the chamher 5 so that any pressure of steam contained within the chamber may readily pass therefrom after passing through the check valve 2.

Formed integral with the body member 4 atthe end opposite the opening 6 is an extension 9 which is provided With a central opening 10 adapted to communicate with the chamber 5. The extension 9 is provided at its outer end with a reduced threaded portion 11 which is adapted to. readily engage with the threaded opening formed in the branch pipe 1 so that the relief cock may be quickly and readily applied to the branch pipe or removed therefrom. The extension 9 is provided with a transverse opening in which is rotatably mounted the valve stem 12 having a trans-. verse opening 13 which is adapted to communicate with the opening 10 whereby communication between the chambero and the branch pipe 1 may be readily established.

The valve stem 12 is provided at one end with a socket 14 in which is threaded the inner end of the operating rod 15. The operating rod 15 is to extend along the side of the locomotive until it reaches the cab and mounted upon the inner end of the rod is a wheel 16 which is adapted to be grasped to rotate the rod 15 and open communication between the branch pipe 1 and the chamber 5 thus relieving the check valve 2 of the steam which passes therethrough, the steam passing outwardly from the chamber 5 through the tube 8. From this it will be readily apparent that should any steam or hot water remain in the branch pipe 1 or the valve 2 after the valve has been closed it may be quickly and readily drained therefrom through our improved relief cock 3. The operating rod 15 is supported upon the sides of the boiler by means of the brackets 17, said brackets being provided with suitable bearings 18 whereby the rod may be readily rotated therein.

It will be understood that our improved relief cock is to be used upon both sides of the boiler and from this it will be seen that in constructing the relief cocks a separate one will have to be made for each side of the boiler as in the relief cock used upon the left hand side of the boiler, the tube 8 will project from the left side of the body 4:, while in the one used upon the right hand side of the boiler, the tube 8 will project from the right side of the body 4:. The chamber 5 which is formed in the body member 4: is provided for the accumulation of dirt and other substance which is contained within the steam and water and as the same collects within the chamber, it may be quickly and readily removed therefrom by unscrewing the plug 7 and permitting the dirt and other accumulations to drop out from the outlet opening 6, and in heating the Chamber 5 a small amount of steam may be turned into the chamber to entirely cleanse the same from the dirt.

From the above description taken in connection with the accompanying drawings, it will be readily seen that we have provided a simple and durable relief orfrost cock which may be quickly and readily applied to the branch pipe of a locomotive boiler so as to release the same of any superfluous steam or hot water and prevent the same from freezing during cold weather.

lVhile we have shown and described the obvious that various changes in the details of construction and in the proportions may the scope of the appended claim.

a What we claim is:

The combination with a branch pipe of a with a central opening, a reduced threaded portion formed upon said extension and adapted for engagement with the branch pipe, a transverse valve stem arranged withi in said extension and having a transverse openlng adapted for communication with the central opening, sald valve having an internally threaded socket at one end and an operating rod having one end removably vengaged with the socket whereby the valve stem may be readily actuated from the cab of the locomotive to establish communication between the branch pipe and the .chamber. preferred form of our invention, it will be i In testimony whereof we hereunto affix our signatures in the presence of two wit- ,nesses.

be resorted to for successfully carrying our invention into practice without sacrificing i 1 any of the novel features or departing from 5 HENRY JAGIELSKI. JOHN J. HOLOHAN.
